Space Station Stage 6A Welcome to Spaceflight Now's comprehensive coverage of the international space station, its full-time residents and plans for the next shuttle assembly mission, flight STS-100/ISS-6A. NASA refers to STS-100 and the Expedition Two crew's on-going work as "Stage 6A" in the space station assembly matrix. This page incorporates that approach. We will post data on upcoming shuttle assembly flights as each stage is completed. E-mail us your comments, suggestions and corrections!
